  • Halophor composition
    Patent number: 4894241
    Abstract: Halophors of a complex of bromine or iodine, a tertiary amide, e.g., dialkylformamide or dialkyl acetamide, and a halide, e.g., alkali metal or alkaline earth metal bromide or iodide, are described. The alkyl groups of the tertiary amide are typically lower alkyl groups, i.e., groups containing from 1 to 4 carbon atoms. Also described are solid biocidal compositions, e.g., fumigants, of particulate, free-flowing inert amorphous siliceous carrier having at least a biocidal amount of halophor admixed with said carrier.
